Summary of the properties of the receptors formed after injection of Asu-unc-38 and Asu-unc-29 cRNAs at different ratios.

The relative maximal currents (Imax) have been normalized to those elicited by acetylcholine on oocytes injected with a 1∶1 ratio of the two cRNAs, due to the large variations in current size seen between individual oocytes. The acetylcholine maximal currents were up to 800 nA to 2 µA. Responses from each oocyte were normalized to 100 µM acetylcholine. ND = Not determined. Results are shown as the mean±S.E., N = minimum of 3. * Due to the small size of the responses seen, it was not possible to derive any quantitative measurements for this receptor∶agonist combination.
